Product Description
Omron D4B-2A11N roller lever limit switch is engineered for high-reliability automation processes in demanding industrial environments. Featuring a robust metal housing, the switch resists mechanical damage and supports an IP67 ingress protection rating, making it dust-tight and water-immersible for sustained operation in harsh factory and outdoor settings.
This limit switch features a roller lever actuator with 2 normally closed (NC) slow action contacts capable of switching AC voltages up to 600V. Its slow action design minimizes mechanical wear and shock loads, thereby extending the switch's lifecycle up to 10 million mechanical operations. The device operates reliably in an ambient temperature range from -40°C to +80°C, making it suitable for both cold storage facilities and hot industrial environments.
The switch supports vertical mounting and incorporates a G 1/2 conduit entry to simplify installation within control panels or machinery. With a compact footprint measuring 43mm width, 40mm length, and 131.3mm depth, it fits well into conveyor systems, robotic automation for precision feedback, lift safety systems, and industrial safety interlocks.
Additional safety is provided by a certified direct opening mechanism that ensures contacts separate safely during contact fusion or failure. This feature enhances operational reliability and worker safety in critical applications.
The durable metal housing ensures robust operation in industrial conditions. IP67 rating provides excellent protection from dust and water ingress. Slow action contact mechanism reduces operational stress and wear. Wide operating temperature range allows use in diverse environmental conditions.
High mechanical life supports millions of operations for long-term use. Vertical mounting and standard conduit entry facilitate flexible installation. Suitable for automation, safety interlocks, conveyor monitoring, and robotics.
Certified standards compliance includes CCC, CE, CSA, IEC, RoHS, TUV, and UL.
This Omron D4B-N series limit switch represents a reliable component choice for industrial automation, manufacturing processes, HVAC controls, and safety systems, supporting consistent performance and minimal maintenance.
